Which equation represents a circle with a center at (-3,-5) and a radius of 6 units?
(x - 3)2 + (y – 5)2 = 6
(-3)2 + (y – 5)2 = 36
(x+3)2 + (y + 5)2 = 6
(x + 3y2 + (y + 5)2 = 36

Step-by-step explanation:

The information we have about the circle is:

center:

and the radius:

the general form of the equation for a circle whose center is at is as follows:

in this case since the center is at , h and k are:

and we substitute this values, and the value of the radius into the general equation:

simplifying this expression we get:
